Xantrex GT500 GFDI (Ground Fault Detector
Interruptor) Technical Bulletin

Rev A
THIS TECHNICAL BULLETIN IS IN ADDITION TO, AND INCORPORATES BY REFERENCE, THE
RELEVANT PRODUCT MANUALS FOR EACH PRODUCT IN THE XANTREX GT100, XANTREX
GT250, AND XANTREX GT500 SERIES. BEFORE REVIEWING THIS TECHNICAL BULLETIN
YOU MUST READ THE RELEVANT PRODUCT MANUALS.
The information in this Technical Bulletin is intended for qualified personnel and
describes how to correctly replace a failed or blown GFDI fuse to maintain
correct ground fault protection.
Qualified personnel have training, knowledge, and experience in:
•
Installing electrical equipment and PV power systems (up to 1000 V).
•
Applying all applicable installation codes.
•
Analyzing and reducing the hazards involved in performing electrical work.
•
Selecting and using Personal Protective Equipment.
DANGER
MULTIPLE SOURCES WITH HAZARDOUS VOLTAGES
• Read all instructions, cautionary markings, and all other appropriate
sections of the Installation and Operation manuals that shipped with your
Xantrex GT100, Xantrex GT250, and Xantrex GT500 inverter before
performing GFDI maintenance on the inverter.
• The inverter is energized from the PV array, from the AC grid, and from an
auxiliary AC source.
• Opening the AC and DC disconnect switches on the inverter does not
remove all power from the inverter.
• Before servicing or maintenance, all three sources must be disconnected,
locked out, and tagged out, and all circuits must be tested to verify that the
inverter is fully de-energized, according to the lock-out and tag-out
procedure in the Installation manual that shipped with your inverter.
• Wait five minutes for the DC bus capacitors, located within the cabinet, to
discharge after removing power. Discharge is confirmed during the lockout and tag-out procedure.
• Normally grounded conductors may be ungrounded and energized when a
ground fault is present or when the GFDI (ground fault detector interruptor)
circuit is defeated.
• Do not operate these inverters without a properly functioning GFDI, and do
not install the GFDI fuse backwards; these actions can allow fire hazardous
fault currents to fail to be interrupted and can cause the GFDI alarm and
inverter shutdown functions to not operate.
Failure to follow these instructions will result in death or serious injury.
FAILURE TO ENSURE THE GFDI CIRCUIT IS INTACT AND OPERATING PROPERLY MAY VOID
YOUR WARRANTY.
INSTALLING THE FUSE BACKWARDS WILL VOID YOUR WARRANTY.

DANGER
HAZARD OF ELECTRIC SHOCK, FIRE, EXPLOSION, AND ARC FLASH
• Always replace a GFDI fuse with same rating and type of fuse (including a
blown fuse indicator pin).
• The new fuse must be placed in a fuse holder with the blown fuse indicator
pin visible before the fuse holder is closed.
• Do not defeat or modify the GFDI circuit in any way.
• Do not install the fuse backwards.
• Do not operate the inverter without a functioning GFDI circuit, including the
correct fuse and proper fuse orientation in the fuse holder.
Failure to follow these instructions will result in death or serious injury.
